、また干渉色の白化作用を減じる。The intensity and purity of the interference colors of pigments of this type vary depending critically on the quality of the metal oxides 1- precipitated on the mica flakes. This main requirement is a uniform thickness of one layer, as well as
- should have as little light scattering as possible and should be formed without cracks. In this regard, not only can cracks occur when the pigment is fired, especially in thick layers, but also the degree of scattering is critical, especially in determining the size of the metal oxide crystals precipitated on the mica. Known to play a role. It is known that the larger the dimensions of the individual crystals of the precipitated metal oxide, the greater the convergence of scattering within one within the relevant region. The diffused light formed at the scattering center within the metal oxide layer is the intensity of the reflected light fraction.
and on the other hand not only reduces the color saturation at the glancing angle, but also reduces the whitening effect of interference colors.
大きすぎる結晶の場合に、真珠様ラスターおよび干渉色
は完全に消失する。In the case of crystals that are too large, the pearl-like raster and interference colors disappear completely.

てこの点で改善された顔料を、提供することが課題とさ
れていた。Pigments produced by known precipitation methods are still unsatisfactory with respect to clarity and tinting power, especially when TlO2 is precipitated as a homogeneous layer on mica flakes, thus providing improved pigments in this respect. The challenge was to do so.
ここに驚くべきことに、TiO2の沈殿をアルミ同時に
共沈殿させる場合に、特に有利な顔料が得られ、それに

存在するところの均質混合1を有する顔料が得られるこ
とが見出された。It has now surprisingly been found that particularly advantageous pigments are obtained when the precipitation of TiO2 is co-precipitated with aluminum, whereby pigments with a homogeneous mixture 1 in which, in addition to TlO2, 5102 and AA'203 are also present. was found to be obtained.

Ti02粒が新しい顔料の顔料表面から溶解し、可溶化
することが見出された。The pigment according to the invention has many advantages. That is, the reduction in scattered light significantly improves the clarity and tinting power of the pigment. This effect seems to depend, at least in part, on the size of the precipitated metal oxide crystals, since when the pigments according to the invention are examined under an electron microscope, these crystals are significantly smaller than conventional pigments. However, the addition of aluminum and silicate according to the invention also produces a clearly more homogeneous and more stable precipitate. It also has very remarkable reproducibility compared to conventional precipitation methods. It has been found that when this pigment is dispersed in water, very few Ti02 grains dissolve from the surface of the new pigment and become solubilized.

Even in the case of very thick layers, which are required for pigments with blue or green interference colors, almost no cracks are observed which lead to a reduction in raster. Overall, the pigments according to the invention have relatively high tinting power against the background of relatively high transparency, low scattered light and dark background. Although these advantages can be obtained with pigments of any grain size, they are particularly significant for grains where light scattering in the metal oxide layer is particularly problematic, i.e., for grains with small grain sizes. It will be done. Therefore, using the method according to the invention, 1
High quality, intensely colored interference color pigments can be produced even with mica powders below 0 μm. Due to the relatively greater stability of the pigment dispersed in water (during which time some TiO2 grains dissolve from the pigment surface and become solubilized), this new pigment can also be further processed in an aqueous suspension or This is particularly advantageous when processing in an aqueous medium.
